srRING SEAT FRAME.

Specification of Letters Patent.

Application filed January 24, 1921. Serial No. 439,333.

cushion seats for vehicles, and it is. the 0bject of the invention to reinforce the front and side edges of the frame by a simple and inexpensive construction which may be readily applied to frames of different widths and proportions. To this end the invention consists in the construction as hereinafter set forth.

In the drawings:

Figure 1 is a plan view of the frame;

Figures 2, 3 and 4 are similar views of the reinforcing members detached;

Figure '5 is a perspective view of a portion of the frame showing the reinforcements applied thereto.

In the present state of the art it is common to form spring frames with marginal or border portions formed of wire over which the fabric covering or skirt of the cushion is drawn. In certain constructions this frame is strengthened by cross bars, to which the springs are attached, but in other constructions there are no such cross bars and consequently there is a tendency for the central portions of the sides of the .border frame to spring inward. With certain construction's heretofore used the front edge of the border frame has been reinforced, but there is still a tendency for the sides to spring, inward, which is objectionable.

With my improved construction I have provided a form of reinforcement which not only stifiens and strengthens the front edge of the border frame, but also reinforces the sides thereof. The reinforcing members employed are of such a character that mostof the elements can be used upon frames of varying width and the one in which these having a central portion adapted to extend parallel to the front side of the border frame, and further provided with the bends C, obliquely-extending portions D and portions E which are arallel to the sides of the border frame. I is a cooperating memher having an angle-bent portion G for lying adjacent to the angle-bend C in the member B. The member F is also provided. with the obliquely-extending portion terminating in a portion I lying parallel to the'front side of the border frame and further having the portion J extending from the angle-bend G to the side of the border frame with an angle-bend K forming a portion parallel with said side of the border frame. L is another reinforcing member having a central portion M parallel with the member B, oblique portions N and N extending oppositely from said central portion and portions 0 and 0 extending Y parallel to the front edge of the border frame.

Theseveral elements above described are secured to each other by clips P, which are bent about the parallel contacting portions of said elements and the border frame. WVhen thus secured, any lateral stress upon the front edge of the border frame will be resisted by the oblique members H, N, N, etc., so that the frame is prevented from losing its shape. Where frames of different widths are constructed, the elements F and L can be used without change, while the element B is only changed in length to suit the change in the dimension of width of the frame. Attention is particularly called to the fact that the sides of the border frame, as well as the front, are reinforced and held; from drawing inward. This is due to the fact; first, that the members B and F together form a rigid strut between the sides of the border frame; and second, the diagonal members H and D, which are substantially in alignment with each other, constitute a corner brace from the center of the sides of the frame to the front thereof. Therefore, great strength is obtained and with the use of comparatively few bracing members.

What I claim as my inventionis:

1. A spring frame comprising a border frame, a reinforcing member having a portion extending parallel to said border frame, and end portions extending obliquely rearward and attached to the sides of said border frame, and a second reinforcing member connected to said first reinforcing member at the bend therein and provided with portions extending respectively to the front and to the side of said border frame.

2. In a s ring frame, the combination with a border rame, of a reinforcing member therefor having a central portion extending parallel to the front edge of said border frame and spaced therefrom, said reinforcin portion having angle-bends therein and ob ique portions extending rearward and outward from said angle-bends and attached to the respective sides of said border frame, and a cooperatin reinforcing member having an angle-hen clip ed to the angle-bend of said first-mentioned reinforcing member and further provided with portions extending respectively to the front and side of said border frame and clipped thereto.

3. A spring frame comprising a border frame, a reinforcement therefor having a portion extending parallel to and spaced from the front side of said border frame, terminating in portions extending obliquely rearward and clipped to the sides of said border frame, and additional reinforcing members extending obliquely between said first-mentioned reinforcing member and the border frame and having portions parallel thereto for engagement of clips.

4. In a spring frame, the combination with a border frame, of a reinforcement therefor comprising a central portion parallel to and spaced from the front side of said border frame, substantially right angle bends in said reinforcement with oblique portions extending therefrom, terminating in portions parallel to the sides of said border frame and clipped thereto, a reinforcement having an angle-bent portion parallel to the angle-bend in'said first-mentioned reinforce ment and secured thereto by clips, an oblique portion extending from said angle-bends to the forward end of the border frame and clipped thereto and a laterally extending portion from said angle-bend to the side of said border frame, terminating in a portion parallel to said side and clipped thereto, and a third reinforcement extending between the parallel portion of said first reinforcement and the front edge of the border frame, said last-mentioned reinforcement having oppositely inclined oblique portions and portions parallel to the border frame for securing thereto by clipping.

5. A spring frame comprising a substantially rectangular border frame, a member having portions parallel to the front edge of said border frame having its end portions extending obliquely rearward to the center of thesides of said frame, and cooperating members having portions extending in alignment with said oblique portion to the front of the border frame and portions extending laterally to the sides of said frame.

6. A spring frame comprising a border frame having front, side and back portions, a bracing member for said front and side portions within said border frame and provided with a body portion extending parallel to the front side of the border frame and having obliquely extending end portions secured to the sides of said frame near the center thereof, members for securing said bracing member to the front side of said frame, said securing members andobliquely extending end vportionsforming a diagonal brace between the front and sides of said border frame.

In testimon whereof I afiix my si nature.
